BRICK 0R TILE FOR FURNACE CONSTRUCTION.

Application filed July 18, 1921.

T 0 all who m 2'25 may concern Be it known that I, CHAnLns l BINNS, a citizen of the United States, residing at Alfred, in the county of Allegany and State of New York, have invented new and useful improvements in Bricks or Tiles for Furnace Construction, of which the following is a specification.

This invention relates to bricks adapted for general application wherever thinness of the wall, together with relatively great stability is desired, where the saving of material is of importance, or thinness of the walls for any other reason may be advantageous, as in furnace construction where thinness of the wall together with great stability is desirable in order that heat may readily pass through the walls without the consequent buckling and disintegration of said walls.

In the construction of walls of the above character of one brick thickness, great difficulty has arisen where ordinary-brick was used because of the small width of the base compared with the height and special difficulty has been met with in the construction of furnaces where the wall. is subjected to great heat and where it is desirable to have a very thin wall in order to allow the heat to pass readily therethrough, since under the influence of heat the walls so constructed from ordinary brick buckle and disintegrate.

An object of the invention is the production of a brick characterized by thinness of wall, while at the same time having a sufficient width of base to render it self support ing.

Another object of the invention is the provision of a brick the base of support of which is made wide relative to the thickness of the brick.

A further object is to provide a brick adapted to be built into a structure, a single brick thick and of comparative great height and which will have the stability of a wall of greater thickness than one constructed of ordinary brick of the same thickness.

Still another object of the invention is the provision of a brick having the over-all dimensions of a standard brick in which the base of support is considerably wider than the thickness of the wall of said brick.

With the above and other objects in view, my invention consists in the improved'brick illustrated in the accompanying drawings,

Serial No. 485,610.

described in th following specification, and particularly claimed, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention relates.

In the drawings accompanying and forming a part ofthis specification, and wherein the preferred embodiment of my invention is illustrated Fi rure 1 is a view in perspective of a brick constructed according to my invention.

Figure 2 is a plan view of the same brick.

Figure 3 is a front elevation of the same.

Figure 4 is a brick having the shape of the abutting halves of two adjoining bricks and adapted to be laid over the joint between two bricks in order to break said joint.

Figure 5 is a modification showing a brick having plane surfaces instead of curved as shown in Figure 2.

Figure 6 shows an application of the bricks of my invention built into a wall which may be used in a furnace. It will be noted that the wall as shown is built of a combination of the forms of bricks shown in Figures 2 and 3. 7

Referring to the drawings in detail, 1 represents a brick formed in accordance with my invention in which there are parallel end faces 52, parallel top and bottom surfaces a and 5 and inside and outside surfaces 6 and 7, the inside surface being concave and the outside surface convexed, thereby defining a body which is offset from or bent out of alignment with the end surfaces 2, and affording a brick of comparative thinness of wall, while at the same time giving it a comparatively great base of support, the base of support being equal to the distance between the line constituting the cord of the arc of the inner surface and the tangent to the outer surface of the brick parallel to said cord. The bricks may be used in wall construction as shown in Figures 6 and 7 which walls may be built up by laying successive layers of the bricks with the bottoms 5 resting on the tops 4 of the next succeeding layer below and with the faces 2 of the bricks of each layer abutting against each other. When used in a furnace it will be readily seen that a wall is in this manner produced through which heat will readily pass and which has a comparatively wide base of support preventing the ready disin 7 the heat passes through it slowly and with difiiculty. Heretofore it has been impracticable to make the wall of said kiln any thinner than-the 4-} inch dimension of the ordinary brick on account of the fact that when laid in courses with-its 2% inch dimension asthe base, the ordinary brick buckles and fails when subjected to the heat ofthe kiln due to insu'llicient width of the. base of support thereof.

In order to get fairly rapidheat con ductivity through-the walls (of the kiln recourse hasheretofore been had to thin tiles set on. edge. The slender-bearing which such, tiles oflier for their own support cause repeated failure. under high temperature due to.I the walls buckling and givingway thus rendering constant repairs necessary. By 'my constructiomthe brick may be given aibaseof support of approximately inches and it. will'be as self-sustaining asthe ordinary brick wall. At the same time the wall of said brick may be madeas thin; as desired withinreasonable limits.

By constructing some of the bricks as shown in FigureQ with the-concave flue side extending: along the surface of the brick and byconstructingsomeas shown in Figure 4, of the shape of the adjoining halves of; two adjacentbri-cks it is possible to lay alternate rows of the one and the other'and, so; build a wall having properly broken joints,

Instead ofconstructingthe brick-with curved su ffacesdt may be made polygonal as shownin- Figure 5; .injwhich; plane surfaces 3'take the place ofthecurved surfaces showndn- :the other figures.

1. An-article of manufacture comprising a building brick. for wall construction having flat parallel coextensive top and bottom facesandflat parallel end faces, the body of said; brick between the ends being bent laterallyout of alignment with said end faces.

2. A; buildingbrick for wall construction comprising a body having parallel end.

its thickness composed of one thickness of bricks arrangedin superposed layers having their body portions when built into the wall curvedlaterally out of alignment with the ends of the bricks and forming verticzltllly extendingchannels in one side of the wa 4-. A. vertical Wall of wide base compared. to.its' thickness comprised of bricks placed in layers one uponanother and end to end insaid layers and having their body portions bent to one sideinterinediate oftheir ends the contracting faces of the super posed layers conforming in contour'with each other.

5-22.11 article of. manufacture consisting of a brick for wall construction .having fiat parallelendfaces and fiat parallel top-.and bottom faces, the body ofsaid brick being bent laterally out of alignment with said end faces. I

6. An article of manufacture comprising a trick for wall construction having-parallel end faces, flat, parallel,- coextensive top'and bottom faces, and a laterally offset portion.

I

10. A wall comprised of; a plurality of superposed layers of brick, said wall having vertical channels formed therein, the bricks of1 alterate layers ending between i th adj as centchannels and in the middle of. the channels respectively.

11. A vertical wall of one brickythickness, con'iprised of, a plurality of; superposed layers of bricks, the bodies of the; bricks.
